Abstract: A permanent magnet motor operated by the magnetic interaction between two or more permanent magnets, and a control system therefor, is provided. The permanent magnet motor may be a piston motor having a magnetic piston assembly mounted on a crank shaft, and a rotatable cam shaft having a cam magnet corresponding to the piston assembly. When the cam shaft rotates about an axis, the poles of the cam magnet alternatingly face the adjacent magnetic pole of the corresponding piston magnet. The magnetic field interactions between the piston magnet and the cam magnet cause the piston to reciprocate within the cylinder. The permanent magnet motor may also be a rotary motor comprising a rotor having a plurality of rotor magnets, and a stator having a stator magnet. A stator motor drives the stator causing the rotor to rotate in response to alternating interactions between magnetic fields of the stator magnet and rotor magnets. A vehicle comprising a permanent magnet motor is also disclosed.
